Uh, the reason "they" say this is because their commercial nitrogen concentrators cannot get past 96%!
I commend you on using 'real' nitrogen...my issue is that consumers are being ripped off under pseudo-science.

PS The answer to my second comment above is this: there are tests that show the N2 molecule as minutely faster permeation times through latex rubber. (not tires) and this has been twisted by vendors in (1) stays inflated longer. (2) proper inflation increases gas mileage, (3) proper inflation is safer. Of course on the last two they leave off the "proper inflation" and say "nitrogen saves money and protects the kids"...

Yeah this whole N2 thing kills me. Soo many strawman arguments in favor, so many dubious claims. Oxidation of vulcanized rubber takes many years, many times longer than the typical lifespan of tire tread. Most modern compressors separate water from the compressed air, it's an easy to do and widely understood technique for paint guns, air tools, etc. Most wheels are alloys, most component parts that any moisture would come into contact with are not ferrous and so wouldn't rust anyway. If they did, heaven help your vehicle if it rained..
